To all/whom t may concern.

Be it lmown that I, ALBERT E. WOODEN, a citizen of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, haveinvented a new and useful Improvement in'Vacuum-Bottles; and Ido hereby declare the following, when taken inconnection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which 'said drawings constitute part of this application,and represent, 1n-

My invention relates to an improvement plurality of tapereddrinking-cups are apshown, I emp plied in'4 nested form tothe shell ofthe bottle so as to form a component part thereof, the o bject of vmypresentl invention being to gromde. means -whereby a standard' vacuumottle may be converted into a bottle of the tygadescribed.

v 1th these ends in view, my invention conslsts in a vacuum bottleconverting-colinto a bottle of the type described.

In carryin out my invention as herein oy' a converting collar havingitsupper and wer ends differentiated in 4diameter and both threaded, itssmaller upper en d 2 being adapted in internal diameter to be screwedover the threaded neck 3 of the domical shell-cap 4 which has. its lowerend formed withthreads 6 to adapt it to be permanentlv screwed upon thethreaded 11%- er end o the 4sheet-metal bottle-shell he larger lower endB'of the convertin collar is threaded and formed'with a spreeAgripping-edge 12 which latter engages with the upper face of theoutwardly turned bead-like rim 13 of the outermost of the' nesteddrinking-cups 14 of .which there are three in the bottle shown, thoughthe number may be varied within limits as desired. The cups having ring10 is slipped down over them and screwed upon the threadedlower portion8 of the converting-collar, whereby the cups as a nest of cups aresecured in place and form a component ture, the rim 13 o the lowermostcup 14 bein drawn firmly down upon a horizontal bearmg-shoulder 15formed between the up'- per and lower ends 2 and 8 of theconverting-ring constituting the characteristic feature of my invention.By providing su'ch a nest of cups and theircoupling-ring with aconverting-collar adapted to fit the threaded neck of a standard vaccumbottle, enabled to convert the same into a bottle of the type in which anest of cups forms a part of its structure.
